Should I take the morning after pill?

I've been on birth control pill for over 10 years and I was traveling and made the mistake of waiting 5 days after I finished my pack to Start the new pack. I had unprotected sex with my boyfriend the first day I started my new pack. He pulled out but I know that's not an effective form of birth control. Should I take the morning after pill? I heard somewhere that you can wait 7 days before you start the new pack but not sure if that's correct. And if I take the morning after pill and continue with my birth control, will the pill still be effective?

No you can't wait the 7 days with yours. The 21 day is the one you wait a week before the next pack. The 28 days the sugar pills take the place of the week wait. You can take the morning after pill and it and the bc pills will be ok together today. You may get some bleeding when its not due and your period might be late. This will be from the morning after pill.
